What shade is used for goggles with the PECU?

Goggles with the PECU (Personal Eye Protection Unit) are designed to protect users from high-intensity light, which can occur during various operations such as welding or working with lasers. The appropriate shade for these goggles is essential to ensure optimal vision protection and comfort while still allowing visibility of the work area.

A shade value of 5 is specifically intended for processes that emit moderate to intense light, providing a good balance of protection and visibility. It effectively filters out harmful radiation while allowing some light through for visibility, making it suitable for tasks where eye protection is critical without completely obstructing the user's view.

In contrast, other shade values either do not provide adequate protection for the associated hazards or may reduce visibility excessively, which could hinder performance and safety during operations. Therefore, using a shade value of 5 ensures that users have sufficient protection while maintaining enough visibility to perform their tasks safely and effectively.
